ASoC: codecs: lpass: fix the order or clks turn off during suspend
[ Upstream commit a4a3203426f4b67535d6442ddc5dca8878a0678f ]
The order in which clocks are stopped matters as some of the clock
like NPL are derived from MCLK.
Without this patch, Dragonboard RB5 DSP would crash with below error:
qcom_q6v5_pas 17300000.remoteproc: fatal error received:
ABT_dal.c:278:ABTimeout: AHB Bus hang is detected,
Number of bus hang detected := 2 , addr0 = 0x3370000 , addr1 = 0x0!!!
Turn off fsgen first, followed by npl and then finally mclk, which is exactly
the opposite order of enable sequence.
